SUBJECT:

ONG0ING STUDIES WITHIN AEOD (N0VEMBER AND DECEMBER, 1986)

Enclosed for your information and use is a listing of currently active or recently completed AE00 studies involving reactor and nonreactor operational events.

Each study is identified by the responsible AEOD organizational unit and engineer, an assignment number, and a brief description of the current status.

When completed, each study will normally be documented and issued as either a technical review (TR) report, an engineering evaluation (EE) report, or a case study (CS) report. The report type will depend on the nature, seriousness, and safety implications of the event, and any associated AE0D recommendations. The completed and issued final study reports are identified in the status column by an AE00 report number.

If additional information or discussion is required for any specific study, please contact either the responsible engineer or the supervisor (Stuart Rubin for ROAB studies, Mark Williams for PTB studies, and Kathleen Black for NAS studies). Additionally, these individuals would appreciate continuing to know about related activities within your offices that should be considernd in either scoping or completing ongoing studies.
